Installing scrapy (openSSL)

I’m using scrapy for couple of months now. I’ve been using it on the couple of machines and never had trouble with it. I used it on Windows xp and 7, I also used it on arch linux and never had trouble installing. Pretty much it was only pip install scrapy and done.

Now I’m trying to set it up on the production server that is using CentOS. As CentOS has python2.4 by default first I made parallel install of python2.7. Also I installed virtualenv for python 2.7 and at that point everything looked like it can’t go wrong, I had my clean environment and had my pip.

But when I tried pip install scrapy it gave ma an error.

I solved with just manually installing 0.12 version
